# Activate a Can’nX license: enter the serial key in the project

Context: Can’nX Cloud: project options, after buying a license on the Can’nX shop

A license purchased on the Can’nX shop, for example for a Link’nX integration such as Sonos, Nuki or 2N, is activated by adding its serial key to the project in Can’nX Cloud (can-nx.cloud). It then applies to the project that contains the gateway.

Intended for the administrator or installer who manages the project in Can’nX Cloud. To understand the padlock on a Link’nX card, see the [Link’nX navigation guide](https://wiki.can-nx.com/en/guides/link-navigation/).

## Before you start

- You have access to the can-nx.shop account used for the purchase.
- Your Can’nX Cloud account shows the project’s **Options** button. Without this button, ask the person in charge of the project to activate the license.

## Find the serial key

The shop labels below are those of its French pages, followed by their meaning.

1. Sign in to your account on can-nx.shop.
2. In **Votre compte** (Your account), open **CLÉS DE SÉRIE** (serial keys).

3. Locate the license by **Nom du produit** (product name) and **Réf de commande** (order reference), then copy its value in the **Clés de série** (serial keys) column. The **État de la clé** (key status) column shows whether it has already been activated.

Keep the key confidential and hide it on any screenshot.

## Add the license to the project

1. In Can’nX Cloud, open the project that contains the gateway concerned.
2. Click **Options**, then **Add an extension**.
3. In the **Register a licence** window, paste the key into **Key**, then click **Confirm**.
4. The **Confirmation** window shows “Use the licence … for the project …”, with the license type and the project name. Check them, then click **Confirm**. **Cancel** closes the window without applying the license.
5. Wait for the **Success!** message.

## Check the result

Open Link’nX on a gateway of the project: the card of the purchased integration should no longer show a padlock. You can then declare the device following the integration’s guide.

## Troubleshooting

| Message or symptom | Action |
| --- | --- |
| **Serial Key not found** | Copy the key again from **CLÉS DE SÉRIE**, without any added space, then try again. |
| **An error has occurred** | Check the open project, then try again once. If the message comes back, contact support. |
| **Options** button missing | Your account does not have the necessary rights on this project: ask the person in charge of the project to activate the license. |
| The card keeps its padlock | Check that the license was applied to the project that contains the gateway open in Link’nX, then follow the [navigation guide](https://wiki.can-nx.com/en/guides/link-navigation/). |

## Contact support

For a key you cannot find in your account, a license applied to the wrong project or a transfer, write to support@can-nx.com stating the order reference, the product and the project name. Do not include the serial key in your message.
